## Overview

Certified A/C Pro Car Air Conditioner Leak Detector Dye is a professional-grade UV dye designed to detect leaks in engine cooling systems. This 1 oz liquid is compatible with nearly all vehicle makes and antifreeze types except GM models using DEX-COOL coolant. When exposed to UV light, the dye fluoresces, making even the smallest leaks visible for quick, accurate diagnosis and repair.

## Description

Certified A/C Pro Engine Cooling Systems UV Dye is an engine coolant UV dye for leak detection. Includes one application of radiator/engine cooling system UV leak detection dye. Safe for use in all vehicle makes and models (except 1996 and newer GM models that use DEX-COOL coolant). Compatible with all types of anti-freeze except GM DEX-COOL coolant.

Review: Great product helped isolate my leak in an impossible to find location otherwise - Works exactly as intended. Had my car out back after a delaminated crank pulley caused the belt to eat into coolant lines going to the oil cooler. Was a pain in my Audi as could not see where the leak was coming from despite my best efforts. Ran this through pressurized the system before taking the coolant system apart to find the leak in a place I wouldnt have seen otherwise. Highly recommended. I used half bottle with great visibility
Review: Did the trick - I ordered the UV dye and a $9.00 uv flashlight from desertcart to troubleshoot a very difficult leak in the cooling system of a fiero. I could see drips of fluid on the frame under the engine, but I could not find any evidence of leaking hoses nor any solid evidence that the leak was coming from the water pump. Just to be on the safe side, I used 2 doses of the dye in the fieros cooling system since it holds about twice as much coolant as a regular car. I waited until dusk and examined the engine with the uv light. The dye showed up bright and clear and I was able to quickly rule out hoses and water pump as the source of the leak. The leak is in a very difficult to view area of the block and behind a heat shield, so I can't get a direct view of the precise place it is leaking, but the drips of dye leave marks even after the fluid dries out so by process of elimination it appears that I have a leak from the head gasket. If I had better access I have no doubt I could see exactly where the leak is, but that would require some disassembly and possibly putting the car on a rack which I haven't done yet. All in all, this stuff worked great for finding a difficult leak. The leak seems to only happen during actual driving. When I stopped and let the car idle while looking for the leak I could smell but not see any evidence of the leak. (possibly drips drying on the hot block and exhaust). With the dye I could clearly see where the fluid leak had been and places where it pooled (around the oil pan lip, etc) where I never would have noticed it without the dye. I also showed the car to a mechanic during the day. The dye was visible under uv light during the day as well. I think I'd still prefer to do real troubleshooting in a light-limited environment, daylight visibility was certainly good enough to confirm findings or get a better look at the problem overall.

### ⭐⭐⭐⭐⭐ Works very well
*by R***D on December 24, 2025*

This works absolutely fantastic. I was chasing a slow coolant leak for about a month & couldn’t figure it out. I bought this & the recommended light + glasses. Found the leak after about 3 days. It glows nice & bright with the recommended light.
